IPTool provides an IP block database tool.

IPtool is a MySQL Database interface that can help you organize IP space.

This is good for ISPs or really big companies that allocate a lot of different IP blocks throughout different locations in their network, and need a useful way to keep track of them.

Dnsmasq is lightweight, easy to configure DNS forwarder and DHCP server. Dnsmasq is designed to provide DNS and, optionally, DHCP, to a small network. It can serve the names of local machines which are not in the global DNS.
The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP for network booting of diskless machines.
Dnsmasq is targeted at home networks using NAT and connected to the internet via a modem, cable-modem or ADSL connection but would be a good choice for any small network where low resource use and ease of configuration are important.
Supported platforms include Linux (with glibc and uclibc), *BSD and Mac OS X. Dnsmasq is included in at least the following Linux distributions: Gentoo, Debian, Slackware, Suse, Smoothwall, IP-Cop, floppyfw, Firebox, LEAF, Freesco, CoyoteLinux and Clarkconnect. It is also available as a FreeBSD port and is used in Linksys wireless routers and the m0n0wall project.
Main features:
- The DNS configuration of machines behind the firewall is simple and doesnt depend on the details of the ISPs dns servers
- Clients which try to do DNS lookups while a modem link to the internet is down will time out immediately.
- Dnsmasq will serve names from the /etc/hosts file on the firewall machine: If the names of local machines are there, then they can all be addressed without having to maintain /etc/hosts on each machine.
- The integrated DHCP server supports static and dynamic DHCP leases and multiple networks and IP ranges. It works across BOOTP relays and supports DHCP options including RFC3397 DNS search lists. Machines which are configured by DHCP have their names automatically included in the DNS and the names can specified by each machine or centrally by associating a name with a MAC address in the dnsmasq config file.
- Dnsmasq caches internet addresses (A records and AAAA records) and address-to-name mappings (PTR records), reducing the load on upstream servers and improving performance (especially on modem connections).
- Dnsmasq can be configured to automatically pick up the addresses of its upstream nameservers from ppp or dhcp configuration. It will automatically reload this information if it changes. This facility will be of particular interest to maintainers of Linux firewall distributions since it allows dns configuration to be made automatic.
- On IPv6-enabled boxes, dnsmasq can both talk to upstream servers via IPv6 and offer DNS service via IPv6. On dual-stack (IPv4 and IPv6) boxes it talks both protocols and can even act as IPv6-to-IPv4 or IPv4-to-IPv6 forwarder.
- Dnsmasq can be configured to send queries for certain domains to upstream servers handling only those domains. This makes integration with private DNS systems easy.
- Dnsmasq supports MX records and can be configured to return MX records for any or all local machines.
Enhancements:
- This release adds some features to the log subsystem: it is now possible to log directly to a file, and to log asynchronously to syslog.
- More detailed logging of DHCP transactions is available.
- DHCP options can now be specified by name instead of by number.
- DHCP configuration can now use information from a DHCP relay agent.
- There are a few minor bugfixes (notably failure of TFTP with --listen-address).
- Some translations have been updated.

CTShaper is a shell-script that helps setting up a traffic shaper, using Linuxs built-in network QoS (Quality of Service) infrastructure.

Have you ever noticed how your SSH/gaming sessions become sluggish when you start downloading something, or how your downloads slow down when you start uploading?

Have you ever been annoyed by other peoples downloads forcing you to wait ages while an email is being sent? Or making your web navigation painfully slow?

Well, if your outgoing link is managed by a Linux router/gateway, then you could benefit from using CTShaper.

CTShaper reduces link latency by preventing packet queues from getting too long on your side (your ADSL or Cable modem) and on your ISPs side (their routers). Long packet queues is what makes your uploads interfere with your downloads, and your downloads interfere with your SSH or gaming sessions.

Additionally, CTShaper sets up four traffic queues with different priorities and configurable flow rates (to have minimum bandwidth guarantees for each class). By default, only traffic with ToS (Type of Service) information gets prioritized (which could be enough, if lots of software had support for it, which they dont), but you can use your firewall (iptables, or an iptables frontend like FireHOL) to "mark" traffic.

The traffic shaper will then prioritize (outgoing) traffic based on those "marks". You can, for instance, give priority to SMTP and HTTP traffic. This will only affect outgoing HTTP and SMTP traffic, but thats enough to make your emails go out faster, and your web navigation more responsive.

PHPlist is a mailing list and newsletter manager that allows posting via a Web page. PHPlist works well when used for announcements, and can handle very large email address lists. Users can sign up to multiple lists, but will only receive a single copy of cross-posted messages.
When signing up, users can identify their geographical location, and messages can be targetted to these. You can add place holders in your email that will be replaced with personal details (such as the persons name).
Users can update their own information, and unlike many other mailing list systems, they can change their email address. HTML emails are supported.
Main features:
- Posting to the mailinglist is via a webpage. It is therefore a one-way announcements system, directed from you to your audience.
- It is designed to be able to deal with a very large amount of email addresses. If a sending fails halfway, the next process for sending simply continues where it left off, without duplicating emails to users.
- Users can sign up to multiple lists. If a message is sent to multiple lists, they will only receive one copy of the email and not as many as the number of lists they are subscribed to.
- Templates. It is very easy to adapt the public pages of the system to fit into your website. You can upload a header and a footer of all pages to make the pages fit your requirements.
- Attributes. You can specify information you want to get from users when they sign up. When sending a message, you can use this information to select the users that need to receive the message. For example you can add geographical information. When people sign up, they can identify the geographical location theyre in and when sending an email you can determine which locations need to receive the message.
- Multiple subscribe pages. You can design your own subscribe pages and you can have different pages allowing users to sign up to a selection of your lists and only enter a selection of your pre-defined attributes.
- Personalisation. You can use the attributes you define in the emails you send, to make every email personal to the user who receives them.
- PHPlist supports HTML emails. If a user indicates they want HTML email they can receive it that way. If unknown the system has a bias to send text emails to users.
- Multiple List managers. One Super user can assign lists to multiple list managers, who can control their own pool of users and lists. The Super user can "prepare" messages that can be chosen by list managers to send to any of the lists they control.
- Easy import and export. Use TAB delimited files to import your existing list of users or to export the users on the PHPlist system for use in your in-house database.
- Personal Details. Every email a user receives will contain a personalised URL to update the users preferences. This way your users can update their own information and your database is always up-to-date. Unlike most other mailinglist managers users can change their email address when updating their personal details. This is a major benefit to both you and your users as many people often change their email address, and this feature makes sure that they dont disappear from your view.
- Attachments. You can add attachments to your message. They will be included in the HTML emails. The users who receive text will get a special URL mentioned in their email telling them where to download the attachment from your website.
- Batch Processing. To facilitate shared hosting environments, you can specify the maximum number of emails to send in a time period you identify. This can also be overridden by ISPs who can set these values server wide to apply to any PHPlist installation on that machine.
- ISP Friendly. Apart from the limit on values for batch processing that the ISP can enforce, there is an additional option for ISPs to suspend sending during busy times in the day.
- Embargoed sending. You can create a message and tell the system to only start sending it at a certain date and time in the future.
- Repetition. A message can be repeated automatically. Currently this is only useful when the message has "filesystem attachments", because they are refreshed at time of sending.
- User management. You can use several in built tools to handle large databases of users. Users can be reminded to confirm their subscription and invalid emails will be found automatically, or fixed whenever needed.
- Bounce handling. Bounces can be processed and users will be automatically unsubscribed when too many emails to them bounced. This can be corrected by the administrator in case the unsubscription was incorrect.
- Automated PDF creation. To ensure users can read the message regardless of mail reader, the message can be automatically converted to PDF and attached to the email.
- RSS feeds. PHPlist can be set up to read a range of RSS sources and send the contents on a regular basis to users. The user can identify how often they want to receive the feeds. For more information about RSS click here
- Easy install. Just copy the files to your website folder, tell the login details of the SQL database and its done.
Enhancements:
- Click tracking has been improved a bit.
- phplist can now also pre-calculate the (bandwidth) size of a mailout.
- Several other smaller issues were addressed.

pdnsd, written by Thomas Moestl, is a proxy DNS server with permanent caching (the cache contents are written to hard disk on exit) that is designed to cope with unreachable or down DNS servers (for example in dial-in networking).
pdnsd solves a frequently occurring problem with dial-up internet connections when the file /etc/resolv.conf changes after wwwoffled (a www proxy server) has been started up. (If youre interested in WWWOFFLE I also have patches available for it here.)
pdnsd allows you to configure one address as the DNS server for all your internet software. This can be localhost, but I personally use a separate machine that Ive configured as a gateway to the internet for my home LAN.
pdnsd project can then be configured to contact your ISPs DNS servers when you make a dial-up connection.
Enhancements:
- This release introduces a new query method: "udp_tcp".
- With this method, a UDP query is tried first and, if the UDP answer is truncated, the query is repeated using TCP.
- There is a new configuration option "use_nss", which can be turned off to prevent lengthy timeouts and stalls in certain situations.
- A bug has been fixed that previously could cause pdnsd to crash when started in debug mode.

Visitors is a very fast web log analyzer for Linux, Windows, and other Unix-like operating systems. It takes as input a web server log file, and outputs statistics in form of different reports. The design principles are very different compared to other software of the same type:
No installation required, can process up to 150,000 lines of log entries per second in fast computers (20MB/s with my log files average length).
Designed to be executed by the command line, output html and text reports. The text report can be used in pipe to less to check web stats from ssh.
Support for real time statistics with the Visitors Stream Mode introduced with version 0.3.
To specify the log format is not needed at all. Works out of box with apache and most other web servers with a standard log format (see the documentation for more information on the format).
Its a portable C program, can be compiled on many different systems. Binaries for Windows systems are in the Download section of this page.
The produced html report doesnt contain images or external CSS, is self-contained, you can send it by email to users.
Visitors is free software (and of course, freeware), under the terms of the GPL license. You dont need to pay to use it. Visitors is supported, if you want a custom version made directly by the original author for a modest price, contact me at antirez (at) invece.org. ISPs may take advantage of the high processing speed.
